Search Problems for searches that begin with s, f, b, and d

I was scratching my head for a bit on this one but eventually I found this before db_query in database.inc:

 *   Valid %-modifiers are: %s, %d, %f, %b (binary data, do not enclose
 *   in '') and %%.

Then I modified the following lines in the site_user_list.module

      if (isset($module_search_restrictions['where'])) {
        $sql_options['where'][] = '(' . $module_search_restrictions['where'] . ')';
      }

to:

      if (isset($module_search_restrictions['where'])) {
      	$module_search_restrictions['where'] = str_replace("%f", "%%f", $module_search_restrictions['where']);
      	$module_search_restrictions['where'] = str_replace("%s", "%%s", $module_search_restrictions['where']);
      	$module_search_restrictions['where'] = str_replace("%d", "%%d", $module_search_restrictions['where']);
      	$module_search_restrictions['where'] = str_replace("%b", "%%b", $module_search_restrictions['where']);
        $sql_options['where'][] = '(' . $module_search_restrictions['where'] . ')';
      }

Looks good now, tell me if anything needs adjustment.
